Exploring the best way to access ViewContainerRef: ViewChild vs Directive

While researching, I came across a recommendation in the Angular Docs that suggests using a directive to access the ViewContainerRef for creating dynamic components. Here is an example of such a directive:

import { Directive, ViewContainerRef } from '@angular/core';

@Directive({
  selector: '[ad-host]',
})
export class AdDirective {
  constructor(public viewContainerRef: ViewContainerRef) { }
}

The documentation also mentioned another approach which involves using ViewChild with {read : ViewContainerRef}, like so:

export class AppComponent {

  @ViewChild('someHashTag', {read : ViewContainerRef}) target: ViewContainerRef;

I am curious if there are any differences or potential issues between these two approaches. Is there any reason why one should not opt for the method that requires less code and effort?

Answer №1

Are you still working on resolving this issue? I have successfully retrieved the ViewContainerRef using a directive similar to the following:

@ViewChild(AdDirective, {static: true, read: ViewContainerRef}) container: ViewContainerRef;

Answer №2

The Directive provides vcref functionality for the initial instance of the Directive. For obtaining vcRef in various parts of the Dom, @viewchild() comes handy.
